Windows update error.How do I block this update????

I was also not able to install KB4048955 after trying about ten times. (I would always see the message "awaiting restart" on the Windows Update section in Settings...and restarting wouldn't get rid of that message). When I tried installing the file manually (after downloading it from the Microsoft Update Catalog) I would get the message "We couldn't complete the updates Undoing changes".

I had recently disable the SearchUI and SearchIndexer Processes because they were hogging resources. In an effort to fix the windows update problem, I re-enabled these processes...and after doing so, KB4048955 installed successfully!

how did you disable them? i see many ways to disable them but not sure which way is the right one.

Just to clarify, my solution would only work if you don't currently see SearchUI.exe as a process running in your Task Manager.

To directly answer your question, you do not want to disable SearchUI. Disabling SearchUI is what was preventing KB4048955 from installing. Re-enabling SearchUI is what allowed KB4048955 to install successfully.
